  • Direct Broadcast data received at MET NORWAY Oslo. Processed by standard processing software to geolocated and calibrated values in satellite swath in received instrument resolution.

  • Sea ice protist diversity from the Arctic Ocean over nearly 40 years. The data is given as percentage of total including the following metadata: expedition, station, core id, gear, old-unit, longitude, latitude, date, ice type, snow, ice, core type, section, core length (cm), section (cm), year, month, sun angel, daylength, PAR

  • The aim of the ECOgaps cruise was to improve our knowledgebase of the region's biological, chemical, and physical properties for the management of the King Haakon VII Sea from the coast of the Dronning Maud Land as part of CCAMLR's WSMPA Domain 4 planning. The focus of this cruise was on Astrid Ridge and Maud Rise. Work was divided into 7 packages: 1) Bird and marine mammal observations 2) Fish community 3) Benthic mapping 4) Zooplankton 5) Primary Production 6) Oceanography 7) Ocean Carbon chemistry. This is merely the preliminary cruise report with general impressions and initial observations and results.

  • Argos tracking data (raw locations) from 13 bowhead whales (Balaena mysticetus) tagged in western Fram Strait in 2017

  • The data show concentrations of persistent organic pollutants in plasma and adipose tissue of adult female polar bears from Svalbard sampled in spring and autumn, 2012-2013. The data was used to explore what determines the variation in concentrations of PCBs, organochlorine pesticides and brominated flame retardants in adult female polar bears from Svalbard. The predictor variables included samplig season, location, feeding habits (approximated by stable isotopes and fatty acid composition), body condition index, fasting status (the ratio between plasma urea in mmol/L and creatinine μmol/L), age (years) and breeding status. All contaminant concentrations are in ng/g wet weight in the data file, but were lipid corrected (concentration/fat%*100) in the publication (except OH-PCBs). Stable isotopes of carbon and nitrogen, d13C and d15N, were analysed in red blood cells and are shown in ‰ unit. Fatty acid composition was determined in adipose tissue and shown in % unit. Breeding status refers to females captured alone (no), or with cubs of the year (coy) or with one or two year old offspring (yrl).

  • Direct Broadcast data received at MET NORWAY Oslo. Processed by standard processing software to geolocated and calibrated values in satellite swath in received instrument resolution.

  • Biogeochemical and environmental data from sea ice (thick second-year/first-year ice and young ice in a refrozen lead).

  • Tracking data from polar bears (N=67) and ringed seals (N=60) in Svalbard that were equipped with various tracking devices and used for analysis that is the basis for the scientific article: Hamilton, C. D., Kovacs, K. M., Ims, R. A. , Aars, J. and Lydersen, C. 2017. An Arctic predator-prey system in flux: Climate change impacts on coastal space use by polar bears and ringed seals. J. Anim. Ecol. 86: 1054-1064. The data set consists of info on animal ID, time, location and species.

  • The data show concentrations of total mercury (THg) in hair from female adult (>4 years, n= 185) and sub-adult (1-4 years; n= 14) polar bears from the Barents Sea subpopulation management regime. The samples were collected in spring of each year between 1995 and 2016 (except 2001 and 2002). Additionally, the samples were analysed for stable isotopes of carbon (δ13C), sulfur (δ34S), and nitrogen (δ15N) to approximate feeding habits (δ13C and δ34S: marine vs. terrestrial diet, δ15N: trophic level). It was assumed that δ34S could be a potential indicator for bacterial mercury methylation. The data were used to explore temporal trend of THg, and how they were affected by changes in feeding habits, and changes in body condition, breeding status, and age. The THg concentrations are given in µg/g hair; and values of all stable isotopes in ‰. Polar bear length and girth are given in cm, and weight in kg. Breeding status refers to females captured alone (n), with cubs of the year (c), or with one or two year old offspring (y, 2y).

  • Ten day binned light-level logger location records for individual common and Brünnich’s guillemots used in the study "Individual migration strategy fidelity but no habitat specialization in two congeneric seabirds ". Raw data for publication. Ten day time steps are counted starting 1 July each year.
